Definitions

  • the invention relates to the preparation of beverages or the like from an extraction material contained in a capsule (portion capsule), for example ground coffee. It relates to devices and methods according to the generic terms of the patent claims, in particular to a portion capsule, a portion capsule body and a combination of a portion capsule and a beverage preparation machine and also to a method for operating a beverage preparation machine and to the use of a portion capsule.
  • Beverage preparation machines for preparing drinks or the like from an extraction material present in a portion pack are known, among other things, as coffee or espresso machines. Because of the extraction process used to make the beverage, they can also be referred to as extraction devices.
  • the portion packs are designed as capsules (portion capsules), in which the extraction material is sealed, for example, in an airtight manner.
  • the capsule is pierced, for example on two opposite sides.
  • An extraction liquid - usually hot water - is then introduced on the first side (injector side).
  • the second side discharge side or extractor side
  • the extraction product is discharged from the capsule.
  • brewing module Such has a brewing chamber in which the capsule is received.
  • Brewing modules are particularly popular, in which the capsule is thrown in and the brewing chamber is closed, for example, by means of an operating lever or by means of a motor.
  • the capsule is automatically removed from the brewing chamber and ejected into a capsule container.
  • Such brewing modules with automatic capsule ejection are usually designed as horizontal brewing modules, i.e. the capsules are thrown in from above, the brewing chamber is closed by a horizontal relative movement of two brewing module parts (injector and diversion unit), the brewing liquid flows essentially horizontally, and the capsule container is below the Brewing chamber formed.
  • WO 2015/048914 describes a brewing module having an extractor (expulsion device; first brewing module part) and an injector (second brewing module part) that can be moved relative thereto, the extractor having a head with mechanical control elements designed as lateral guide means, which have a first and a second track for a defining a capsule collar, and wherein the extractor further forms a seat which limits downward movement of the capsule when the capsule collar is on the first web. Furthermore, the lateral guide means are connected to the head, and the injector has a mechanical control element designed as a return element, which is designed to act on the capsule collar when the brewing chamber is opened and to move it into the second path.
  • aluminum and plastics for example polypropylene
  • capsule materials aluminum capsules bring a very good shelf life (aroma protection) of the extraction material, but are very energy-intensive to produce.
  • Polypropylene capsules are advantageous in terms of energy consumption and disposal, but place increased demands on the piercing mechanism and aroma protection. Both aluminum and plastics are criticized as capsule materials, the former in particular because of the high energy consumption during production, the latter in particular because of the waste problem.
  • a coffee portion capsule is known from WO 2010/118543, which has approximately the shape of a cube, is made of plastic and, in contrast to the known cup-shaped capsules, does not have a collar running around the top surface.
  • a peripheral collar is required, among other things, for closing the capsule with a film serving as a lid.
  • the collar is needed to provide an energy director accommodate. If the capsule is closed by thermal sealing, the collar is necessary so that the lid rests on a sufficiently large area.
  • a curved cover is used and the closure is effected, for example, by means of ultrasonic cut-off welding.
  • the capsule produced according to the teaching of WO 2010/118543 consists of a capsule body (with base area, side wall and collar area) and a lid and therefore has a gap between the upper and lower cover surfaces, regardless of its ("cube") shape Defined planes arranged, circumferential welding brow, which forms only a minimal collar and whose expansion / lateral protrusion is significantly reduced compared to the collar of known capsules.
  • bio-plastics have also been discussed as capsule materials. On the one hand, this refers to plastics that are made from a renewable raw material (so-called bio-based plastics). On the other hand, bio-plastics can be plastics that are biodegradable (so-called biodegradable plastics). The plastics proposed for the manufacture of portion capsules are biodegradable and some contain a proportion of bio-based plastics.
  • biodegradable means biodegradable according to the ENI 3432 standard (as of the end of 2019), and “bio-based” means “made from renewable raw materials, not on a fossil basis”.
  • bio-plastics in particular biodegradable plastics, have the property that they soften at relatively low temperatures and therefore already have a certain flowability at low temperatures (low glass transition temperature), but that they have to be heated to a high degree before they are completely are flowable (ie the melting temperature, where defined, is not particularly low). Softening even at relatively low temperatures results in a loss of mechanical stability of the capsule during the brewing process with a hot liquid. And if during the brewing process inside the capsule a right considerable pressure prevails, the capsule must be designed in such a way that its mechanical stability is sufficiently high.
  • WO 2017/017704 describes capsules made of biodegradable material, which have reinforcing means to ensure mechanical stability of the capsule, which allows the capsule to be subjected to high internal pressures.
  • filamentary material can be spirally applied to the outer surface of the side wall of the capsule.
  • Capsules with reinforcing agents are also known from WO 2016/087981. There, profiles running parallel to the axis of the capsule are provided on the side wall of the capsule.
  • bio-plastics in particular biodegradable plastics, have a modulus of elasticity at room temperature that is significantly greater than the modulus of elasticity of plastics that are conventionally used as encapsulation material.
  • the modulus of polypropylene is typically between 1000 Pa and 2000 Pa, while the modulus of some bio-plastics is over 4000 Pa.
  • capsules of the same shape made of such a bio-plastic exhibit less deformability at room temperature than capsules made of polypropylene.
  • bio-plastics in particular biodegradable plastics, are more brittle at room temperature than plastics that are conventionally used as encapsulation material.
  • Beverage preparation machines should be usable. In particular should
  • a further possible object of the invention is to create a portion capsule and a portion capsule base body which allow movements of the portion capsule in a brewing chamber of a beverage preparation machine for which a maximum force to be applied is relatively small.
  • a further possible object of the invention is to create a portion capsule and a portion capsule main body, through which a user who creates movements of the portion capsule in the brewing chamber by hand has a particularly smooth and/or low-jerk user experience.
  • a further possible object of the invention is to create a portion capsule and a portion capsule base body by means of which movements of the portion capsule in the brewing chamber can be generated particularly easily and/or with little jerk, in particular by hand.
  • a further possible object of the invention is to create a portion capsule and a portion capsule base body which make it possible to use a drive, for example an electric motor, which has a relatively low maximum force.
  • a further possible object of the invention is to create a corresponding combination comprising a portion capsule and a beverage preparation machine.
  • a further possible object of the invention is to create a corresponding method for operating a beverage preparation machine.
  • a further possible object of the invention is to create a use of a portion capsule to reduce a maximum force to be applied for generating a relative movement of the portion capsule in a brewing chamber of a beverage preparation machine.
  • a mechanical control element for example a mechanically prestressed lever arm
  • the mechanical control element can be a return element that allows the portion capsule to be pulled back from a brewing position to an ejection position.
  • a greater force is generally required than for the previous movement of the effective area of the mechanical control element along the side wall of the portion capsule body.
  • a reduction in this maximum force makes it possible to use a weaker or smaller-sized motor and/or to reduce the effort that a user has to operate in the case of manual operation.
  • portion capsule is now made from a material that has a relatively high modulus of elasticity and thus only deforms relatively little under the circumstances described, then the necessary maximum force will be relatively large. Accordingly a relatively powerful motor would be necessary or a user would have to exert greater force in the case of manual operation.
  • At least one ramp element is provided on the portion capsule, more precisely on the portion capsule base body.
  • the mechanical control element can be pushed outwards beforehand by means of the ramp element, so that when the capsule collar is reached, on the one hand, the mechanical control element is already pushed far outwards and/or on the other hand the side wall of the portion capsule base body is already slightly compressed. Both effects mean that the maximum force required for the movement (in particular when moving the effective range of the mechanical control element over the capsule collar) is lower than would be the case without the ramp element.

  • the axis runs centrally through the bottom area and through the opening and defines an axis direction pointing from the bottom area through the opening, and wherein a distance measured perpendicularly to the axis is referred to as the axis distance, wherein the side wall has at least one ramp element through which at least one Ramp area is defined in which the center distance of Outer surface along the axis direction is continuously or discontinuously increasing.
